Allergies & Food Intolerances

Dr Gunter has a special interest in both allergies and intolerances. Many health problems go unrecognised for what they are, and these problems are frequently due to adverse food reactions. She tests for both allergies (immediate onset reactions) and Sensitivities (delayed onset reactions), depending on what is required. An initial consultation is done prior to testing to ensure that the correct test is done based on symptoms and history.


Allergy testing is done by sending your blood to the Laboratory to test for reactions to airborne allergens and/or food allergies. Allergies are characterised by an immediate onset of symptoms including itchy palate and skin, swelling of lips, mouth and throat, Urticaria (swelling of skin) and certain cases of Asthma. Allergies are mediated by Immunoglobulin E, which is what is tested for in your blood.

Food Intolerances or Food Hypersensitivity Reactions 

Food hypersensitivity reactions, also known as Intolerances are different from allergies in that the reaction is delayed onset (not immediate). They are characterized by symptoms including chronic post nasal drip & cough, eczema, joint pain, bloating & IBS, brain fog, chronic headaches.

Testing is done on both adults and children (usually from 12 months of age). In children younger than 12 months who are breast feeding testing is done on the Mother. The food intolerance test is a blood test done in the office. It takes 1 hour to obtain the results, and patients receive a full food plan thereafter. Please email us for more details:


Dear Dr Gunter,
I just wanted to let your know that our daughter’s skin has improved remarkably. In fact, the eczema around her eyes started clearing within 2 days of us taking her off gluten, eggs and fish and now the eczema is virtually entirely gone.
So I just wanted to let you know and say thanks very much for the help, the improvement in her skin truly has been remarkable! -Kind regards, Stefan Bolling


There is some discrepancy in the allergy community regarding routine IgG testing (like Alcat etc)- (which is not an IgG4 ELISA). IgG testing is too broad spectrum in its assessment and can show false positive results. It is only the IgG4 subfraction test which is specific for intolerances that is used and this test is only manufactured in Germany and imported into South Africa.
